Health Information
MedlinePlus Guide to Healthy Web Surfing
What should you look for when evaluating the quality of health information on Web sites? Here are some suggestions based on our experience.
Consider the source—Use recognized authorities
Know who is responsible for the content.
- Look for an "about us" page. Check to see who runs the site: is it a branch of the Federal Government, a non-profit institution, a professional organization, a health system, a commercial organization or an individual.
- There is a big difference between a site that says, "I developed this site after my heart attack" and one that says, "This page on heart attack was developed by health professionals at the American Heart Association."
- Web sites should have a way to contact the organization or webmaster. If the site provides no contact information, or if you can't easily find out who runs the site, use caution.
Focus on quality—All Web sites are not created equal
Does the site have an editorial board? Is the information reviewed before it is posted?
- This information is often on the "about us" page, or it may be under the organization's mission statement, or part of the annual report.
- See if the board members are experts in the subject of the site. For example, a site on osteoporosis whose medical advisory board is composed of attorneys and accountants is not medically authoritative.
- Look for a description of the process of selecting or approving information on the site. It is usually in the "about us" section and may be called "editorial policy" or "selection policy" or "review policy."
- Sometimes the site will have information "about our writers" or "about our authors" instead of an editorial policy. Review this section to find out who has written the information.
Be a cyberskeptic—Quackery abounds on the Web
Does the site make health claims that seem too good to be true? Does the information use deliberately obscure, "scientific" sounding language? Does it promise quick, dramatic, miraculous results? Is this the only site making these claims?
- Beware of claims that one remedy will cure a variety of illnesses, that it is a "breakthrough," or that it relies on a "secret ingredient."
- Use caution if the site uses a sensational writing style (lots of exclamation points, for example.)
- A health Web site for consumers should use simple language, not technical jargon.
- Get a second opinion! Check more than one site.
Look for the evidence—Rely on medical research, not opinion
Does the site identify the author? Does it rely on testimonials?
- Look for the author of the information, either an individual or an organization. Good examples are "Written by Jane Smith, R.N.," or "Copyright 2003, American Cancer Society."
- If there are case histories or testimonials on the Web site, look for contact information such as an email address or telephone number. If the testimonials are anonymous or hard to track down ("Jane from California"), use caution.
Check for currency—Look for the latest information
Is the information current?
- Look for dates on documents. A document on coping with the loss of a loved one doesn't need to be current, but a document on the latest treatment of AIDS needs to be current.
- Click on a few links on the site. If there are a lot of broken links, the site may not be kept up-to-date.
Beware of bias—What is the purpose? Who is providing the funding?
Who pays for the site?
- Check to see if the site is supported by public funds, donations or by commercial advertising.
- Advertisements should be labeled. They should say "Advertisement" or "From our Sponsor."
- Look at a page on the site, and see if it is clear when content is coming from a non-commercial source and when an advertiser provides it. For example, if a page about treatment of depression recommends one drug by name, see if you can tell if the company that manufactures the drug provides that information. If it does, you should consult other sources to see what they say about the same drug.
Protect your privacy—Health information should be confidential
Does the site have a privacy policy and tell you what information they collect?
- There should be a link saying "Privacy" or "Privacy Policy." Read the privacy policy to see if your privacy is really being protected. For example, if the site says "We share information with companies that can provide you with useful products," then your information isn't private.
- If there is a registration form, notice what types of questions you must answer before you can view content. If you must provide personal information (such as name, address, date of birth, gender, mother's maiden name, credit card number) you should refer to their privacy policy to see what they can do with your information.
Consult with your health professional—Patient/provider partnerships lead to the best medical decisions.

Privacy and Your Health Records
You have privacy rights under a federal law that protects your health information. These rights are important for you to know. You can exercise these rights, ask questions about them, and file a complaint if you think your rights are being denied or your health information isn't being protected.
Who must follow this law?
- Most doctors, nurses, pharmacies, hospitals, clinics, nursing homes, and many other health care providers
- Health insurance companies, HMOs, most employer group health plan
- Certain government programs that pay for health care, such as Medicare and Medicaid
Ask to see and get a copy of your health records
You can ask to see and get a copy of your medical record and other health information. You may not be able to get all of your information in a few special cases. For example, if your doctor decides something in your file might endanger you or someone else, the doctor may not have to give this information to you.
- In most cases, your copies must be given to you within 30 days, but this can be extended for another 30 days if you are given a reason.
- You may have to pay for the cost of copying and mailing if you request copies and mailing.
Have corrections added to your health information
You can ask to change any wrong information in your file or add information to your file if it is incomplete. For example, if you and your hospital agree that your file has the wrong result for a test, the hospital must change it. Even if the hospital believes the test result is correct, you still have the right to have your disagreement noted in your file.
- In most cases the file should be changed within 60 days, but the hospital can take an extra 30 days if you are given a reason.
